Before Odoo saas-14.4, one should call `_get_http_domain()` on website to get
its domain. Indeed, that method was in charge of cleaning that domain, as it
was done with commit [1].
Since Odoo saas-14.4, that cleaning is automatically performed on domain before
saving it into database, thanks to commit [2].
Thus, we can now remove the `_get_http_domain()` and use directly the domain as
it is considered clean.
Note that migrated databases coming from version older than Odoo saas-14.4
could still have an incorrect domain (trailing slash, no scheme..).
This will be handled during migration with [3].
